The pair's characters Bart McQueen and Sinead O'Connor certainly endured a bumpy ride before getting together properly, which inspired a fairground dodgems theme for the new shoot.
Pictured: Jonny and Stephanie and Inside Soap.
While Bart and Sinead are currently happy on screen, the soap duo told the magazine that things may not stay that way.
Clarke explained: "There's something big coming up for Bart, which will really give me the chance to put my acting skills to the test. It's going to be quite dark and gritty."
Davis added: "There's going to be another big, emotional journey for those two - but that's good for us, because we like arguing!"
The stars also explained how they have struck up a strong friendship in real life after working together for well over a year.
Clarke agreed: "Steph and I get on really well. We go out for dinner with some of the other guys in the cast all the time, and it's brilliant."
The Hollyoaks photoshoot is part of a collection of exclusive Valentine's features in the new issue of Inside Soap, which is out on shelf now. Stars from Coronation Street, EastEnders, Emmerdale and Neighbours also feature.
